MIG Welding Aluminum
I know you can weld aluminum with a MIG welder, but do you absolutely need a spool gun? I've read a few manuals that just say use 100% argon gas and a larger tip for expansion and so on and so forth. No mention of a spool gun. So, does it really work? If not, how much do spool guns (and related/required accessories) cost?
